Installation Instructions

Features & Benefits
of Thermafiber
®
Mineral Wool
Insulation
Attics: New Install
or Topping Up
1. Seal Air Leaks.
Seal air leaks in the ceiling below the
attic. These include exterior and interior
walls below as well as electrical, lighting,
plumbing, ventilation ductwork, chimneys
and other services through the ceiling
that enter the attic.
NOTE: Consult applicable building codes for
requirements on sealing around heat emitting sources
such as chimney, pot lights, etc.
2. Install AtticMate
®
Rafter Vents. Staple Owens
Corning
®
AtticMate
®
rafter vents to roof
deck in every roof joist cavity around the
perimeter of the attic. Ensure vents extend
beyond the vertical height of the insulation
being installed in the attic.
4. Wiring, Plumbing &
Services. Splice insulation for
electrical wiring and cut to shape around
plumbing, lighting & other services to
ensure a tight, secure fit.
Note: See clearance minimums in the Insulating
Around Fixtures section.
3. Install Batts.
Select the Thermafiber
®
UltraBatt
™
insulation that is the same thickness as
your ceiling joists. First install batts at
outer edge of attic, ensuring the top of
your exterior walls are covered, then work
towards the middle of the attic.
1. Installing Batts.
Install Thermafiber
®
UltraBatt
™
insulation
between studs. Where necessary, cut to
length & shape around obstructions in the
stud cavity filling all voids.
1. Sealing Air Leaks.
Seal air leaks between unheated & heated
areas before insulating i.e. garages,
basements, crawlspaces, bumpouts.
Leaks can include framing, electrical
wiring, plumbing, ductwork, cables, and
any other services.
2. Wiring, Plumbing &
Services. Splice insulation for
electrical wiring and cut to shape around
plumbing, lighting & other services to
ensure a tight, secure fit.
2. Applying Vapor Barrier.
Apply a vapor barrier to the underside of
the floor adjacent to the heated space.
Consult applicable building code for vapor
barrier requirements and proper location.
3. Installing Vapor Barrier.*
Install a continuous vapor barrier over
entire wall area. Overlap the joints by at
least 6".
IF vapor barrier is also an air
barrier, seal all joints with approved caulking or
tape and ensure all electrical, plumbing, lighting & other
services in the wall are air sealed to the vapor barrier.
* Consult applicable building code for vapor barrier
requirements and proper location
3. Install Batts.
Place batts between floor joists, where
they will stay in place temporarily. Splice
insulation for electrical wiring and cut
to shape around obstructions in the joist
cavity filling all voids.
4. Apply Wall Finish.
Apply drywall or other wall finish on top
of the vapor barrier.
4. Hold Batts in Place.
To hold insulation in place, nail wire
mesh to the underside of the floor joists.
Alternatively, an exterior sheathing finish
can be installed.
5. Adding Additional
Layers. To achieve the desired
R-value, install multiple layers of
Thermafiber
®
UltraBatt
™
insulation
perpendicular to the layer below. Minimum
total R-value recommended
for an attic is R60.

1. Cut a notch the size and
depth of the electrical box out of
the Thermafiber
®
batt.
1. Measure the distance of the
wire from bottom plate, stud,
joist or previous Thermafiber
®
batt installed.
2. Slide the batt in from the
side so the box sits within in the
cut out.
2. Measure the same distance
on the batt and splice the batt
the depth of the wire’s location.
1. Cut and/or notch the
Thermafiber
®
batt around the pipe.
Slide the batt in-behind the pipe
ensuring a tight and secure fit.
3. Install the batt into the cavity
fitting the wire in the splice.

CAUTION: Building, electrical, fire and other applicable codes shall be complied with.
All heat emitting devices, such as fuel burning appliances, chimneys, pipes, ducts and vents
to these appliances shall maintain a minimum clearance of 50 mm between these devices
and the insulation. Recessed light fixtures, unless designed for the purpose, shall not be
installed in insulating ceilings.
